v CHANGE-MAKING MACHINE.

Specification of Letters Patent. Patented Sept. 17, 1918.

Application filed November 21 1916. Serial No. 132,666.

To all whom it may concern:

Be it known that I, BENJAMIN F. DAVIS, a citizen of the United States, residing at Lisbon, in the county of Lake and State of Florida, have invented new and useful Improvements in Cl1ange-Making Mach1nes,of which the following is a specification.

This invention relates to coin controlled machines of the class designed for the purpose of automatically making change.

The object of the present invention is the provision of a machine of this character preferablylocated within the housing of a coin controlled machine, for the purpose of enabling the purchasers to obtain change for use in said machines and thereby increase the profits.

- Another object of the invention is to provide a mechanism which may be so locked Within the housing of a vending machine that coins used in the said machine will be conveyed to the change making mechanism for the purpose of providing change. 1

Another object of the invention is the provision of .a change making machine which may be so adjusted as to deliver a predetermined number of coins of a like denomination, at one operation of the machine.

A still further object is the provision 'of a machine of this class in which the mechanism is locked against operation, until the depositing of a coin of the proper denomination and after such operation the machine may be again automatically locked.

With the above and other objects in view which will appear as the invention is more fully described, the said invention consists of the following novel combination and arrangement of parts, shown in the 516C011):

panying drawings and set forth in the appended claims.

In the drawings; 1 Figure 1 is a sectional view through the bottom portion of a vending machine casing,

having the improved change making machine constituting the present invention located therein.

Fig. 2 is a plan view of the invention removed from the casing;

Fig. 3 is a central longitudinal sectional view through the subject matter of Fig. 1;

receiving therein the coin.

Fig. 4 is a transverse sectional view on the line 4-t of Fig. 3, showing the machine within the casing;

Fig. 5 is a horizontal sectional View on the ling 55 of Fig. 1 with the casing removed; an

Fig. 6 is a detail perspective view of the pivoted locking lever.

The invention set forth is primarily intended for use as a change making machine, but it is obvious from the following description that the machine may be arranged for use as a. coin counting machine, it being necessary to simply adjust the machine to enable it to deliver any predetermined number of coins upon a 'slngle operation of the mechanism.

In the practical form of the invention, the machine is preferably located within the housing 10 of a vending machine (the mechanism of which is not illustrated) alwith a separate housing for independent use. The machine as herein illustrated comprises a suitable frame 11, mounted upon support ing legs 12 by means of which it is secured to the bottom of the vending machine casing by screws or other fastening devices 13. The frame of the machine includes the table let upon which is supported the coin hopper 15, the said hopper being in communication with a compartment 16 of the vending ma chine, this con'ipartment being adapted to receive the coins deposited in the said. vending machine and conveyed therefrom to the hopper 15. As above stated the hopper is supported upon the table 14, the said support consisting of a coin stacking cylinder 17, secured to or formed upon the hopper and connected therewith. Slidably mounted beneath the cylinder 17 is a coin slide 18, provided with an elongated opening 19 adapted to travel across the opening in the bottom of the cylinder 17 for the purpose of As stated the opening 19 is elongated, the purpose of which is to permit the rear portion of this opening to pass beyond the cylinder in order to insure the reception of a coin therein, the forward portion of this opening being adapted to register with the opening in the chine casing.

bottom of the cylinder 17. In order to pro-v vide for the varying thicknesses of new coins and used coins, the slide 18 has the rear portion of the opening 19 beveled upon its upper side as shown at 20, in order that it will not engage the entire thickness of the coin, so that should a worn coin be positioned in the opening 19, the beveled portion of the opening will wedge under the coin next above and raise it from position within the opening 19, permitting only the coin engaged by the inner wall of the opening to be delivered. Located beneath the slide 18 is a guide 21, provided with an opening 22 therein, the said opening being located in advance of the cylinder 17. When the slide 18 is brought forward the coin within the opening 19 will be brought into position with the opening 22 of the guide and pass therethrough into the change. delivery chute 23 having communication with the outside of the casing 10.

Secured to the forward end of the slide 18 is a cross bar 24, the said bar being reduced at either end for the purpose of providing a pivotal connection 25 with pitman 26, the

said pitman forming an operating hook for v the slide 18. The ends of the pitman opposite the pivot 25 are connected to crank arms 27 and 28 mounted upon the shaft 29 of the slide bearing mechanism, the said shaft being mounted in suitable bearings in the frame of the machine. Securely mounted upon the shaft 29 is a gear 30, adapted to mesh with a gear 31 carried by the shaft 32 also having bearings in the frame 1, and provided upon its outer end with a squared portion for the reception of an operating lever 33 located upon the outside of the ma- 1 Mounted upon the shaft 32 is a beveled pinion 33', the said pinion being meshed with a similar pinion 34 mounted upon the end of the shaft 35, extending longitudinally of the machine into the hopper 15. In order'to provide bearings for the shaft the hopper is provided with acl'oSS bar 36, and extending upwardly from this cross bar is a bearing 37 for one end of the shaft 35, the said shaft extending through a suitable bearing 38 provided in the wall of the hopper. Located upon the inner end of the shaft 35 is a beveled pinion 39, engaging a pinion 40 mounted upon a short shaft 41 which also has a bearing in the cross bar 36. The opposite end of the shaft. 41 is provided with a revolving agitator 42, the agi tator being of a shape to conform to the semi-circular bottom of the hopper 15 and being so arranged in position as to operate over the bottom of the hopper to direct the coins into the stacking cylinder in proper position to be acted upon by the slide 18.

Mounted upon the shaft isa gear 43, which engages thegear 44 secured to the shaft .45. Also mounted upon this shaft is a gear 46 meshing with the gear 47 mounted upon the shaft 48 having bearings within the side bars of the frame 11. The construction just described is to provide means for rotating the shaft 48 at a speed considerably greater than that of the'shaft 32. The shaft 29 which is driven by the gear 30 from the gear 31, has also mounted thereon at its opposite end a pinion 49, the said pinion engaging the gear 50 mounted upon the shaft 51. As clearly illustrated in Fig. 1 the gear 49 is of a diameter considerably smaller than the gear 50 so that the said gear 50 will be operated only once to a number of revolutions of the gear 49: The purpose of this is to regulate the number of coins delivered from the hopper by a single operation of the slide opera-ting gearing. For illustration should the machine be attached to a vending machine operated by pennies, the change making machine will be set soas to deliver five pennies in exchange for a nickle deposited within the machine. In this event the pinion 49 will rotate 5 times to one rotation of the ear 50 consequently one rotation of the handle 33.

Pivotally mounted at 52 upon the machine frame is a locking lever 53, thislever being provided with an outwardly and downing upwardly from the lever 53 is a horizontal and laterally extending stop arm 54', the said arm being located in the 'path of movement of revolving sto mounted upon the sha t 48, so that when the arm 54 is engaged with either one of the arms 55. the gearing mechanism will be locked against movement. The lever 53 extendsforwardly along the side of the machine and is provided with an inwardly extending cam engaging arm 56, the said arm being adapted to be acted upon by the lever operating cam 57 mounted upon the outer end of the shaft 51. It will be seen by reference to Fig. 1 that when the cam 57 is revolved. in the direction of the arrow its engagement with the arm 56 will press the lever 53 downwardly for the purpose of permitting the continued operation of the gearing and the ejection of the coin as will be hereinafter described. Carried by the outer end of the lever 53 is a coin pocket 58, and when the said lever is in its locking position this pocket registers with the lower open end of the coin chute 59, preferably located in the side of the casing 10 for the purpose of receiving the coin to be changed. The depositing of this coin within the pocket 58 will cause this end of the lever 53 to be depressed a sufficient distance to disengage the arm 54 from the revolving stop arm 55 and permit the rotation of the gearing by engaging arms 55' ejected. Secured to the bottom of the machine is a stationary arcuate coin ejector arm 60, the said arm being adapted to travel in a guiding slot 61 formed in the pocket 58. Mounted upon the inner surface of the arm 60 is a lug 61, and when the lever 53 is depressed this lug will come in contact with the edge of the coin and lift it from the pocket 58, for the purpose of permitting the weight 55 to overbalance this end of the lever, and return the same to its locking position after the cam 57 has made a complete revolution. To further provide against the unlawful operation of the machine the lever 53 is provided with a stop 62, located in the path of a pin 63 formed by an extension of the pivot, by means of which the crank arm 28 is engaged with one of the pitmen 26.

It is thought from the foregoing description that the construction and operation of the ll'lflChlIlB will be apparent, a further brief description of the operation however will be given. Upon the depositing of a coin, for example afive cent piece, within the chute 59, the said coin will be guided into the pocket 58 of the locking lever 53. The weight of thi coin will sufiiciently overbalance the counterbalance weight to permit disengagement of the arm 5t fron'1 the arm 55', to allow the operator to rotate the handle 33 and through it the gearing for operating the slide 18 for the delivery of the coins within the chute 23. If as stated a five cent piece is used the ratio of the gears 49 and will be such as to cause the slide to be rcciprocated five times to a single revolution of the shaft 51 and consequently the cam 57. Upon each reciprocation of the slide a penny will be delivered from the hopper 15 into the chute 23 so that the person operating the machine will receive five pennies in exchange for a five cent piece upon a single operation of the machine. A soon as the is released to permit the operation of the gears the cam 57 will be rotated and through its engagement with the arm 56 will depress the locking lever 53 and disengage the stop 62 from the pin 63 permitting the reciprocation of the slide 18. As the lever 53 is further depressed the lug 61 carried by the stationary ejector (30 will engage the coin and I'BIDOXQ it from Within the pocket 58. By this time the cam 57 has made a complete revolution and the disengagen'ient of the coin from the pocket will cause the counterbalance weight 55 to return the lever 53to its initial position and automatically relock the machine.
